Evidence on the hierarchical multidimensional nature of behavioural job crafting

While to date job crafting has been conceptualised as consisting of behaviours aiming at seeking more resources, decreasing hindering demands, and seeking more challenges, recent research suggests that individuals may restore the fit between their demands and preferences also by optimising their demands. Accordingly, optimising demands has been introduced in the resource‐based perspective to job crafting as an additional strategy that aims at making the work processes more efficient, simplifying procedures and eliminating obstacles. In this paper, we explore and provide evidence for the validity of a four‐factor, hierarchical structure of behavioural job crafting constituted by increasing resources, seeking challenges, decreasing demands, and optimising demands. Moreover, our results provide initial evidence suggesting that overall job crafting may be more strongly characterised by effortful actions to expand the work characteristics rather than to reduce them
